Step-by-step explanation:
Volume:
πr2h
=π×52×8
= 200π
= 628.31853071796
rate= 5 mi
height= 8 mi
to find:the volume of the cylinder.
solution:[tex]v =\pi {r}^{2} h[/tex]
[tex]v = \pi \times {5}^{2} \times 8[/tex]
[tex]v = 628.3185307 \: {mi}^{3} [/tex]

Answers
The function 2 represented by the equation f(x) = -(x - 2)² + 5 has the larger maximum.
How to complete the function?The functions are given as:
Function 1
f(x) = -(x - 4)² + 1
Function 2:
f(x) = -(x - 2)² + 5
A quadratic function is represented as a (x - h)² + k, when a is negative then, the vertex of the function is a maximum. In both functions, the value of a is -1. This means that both functions are at a maximum
The values of k in both functions are k = 1 and k = 5. By comparison, 5 is greater than 1. Therefore, function 2 has larger maximum.

Answers
Answer:
x=2, y=-4
Step-by-step explanation:
If you put a vertical or horizontal line straight through the shape and it looks the same, then it is symmetrical. You can put a symmetrical line both vertically AND horizontally. To do this, you just need a line going through the points at the tips and the points at the sides of the quadrilateral. A line that is vertical will be an x=, because it only covers one x-value. So, the line for x will be x=2, because it goes through both tips of the quadrilateral. A horizontal line will be y= because it only covers one y-value. So, the line for the horizontal line will by y=-4, because this goes through both sides of the quadrilateral.

2nd: you minus -12x on both sides on 28 like an equation but you don’t actually minus the 28 but leave it as -12x after that you should get the numbers below
3rd: -2y=-12x+28 you can’t have negatives y so you do this step down below
4th: -1 (-2y-12x+28) multiple each number
And you get 2y=12x+-28
5th: divide 2y on every number aka on (2y, 12x, -28)
6th: y=6x-14 is what you should get!

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Gabriel is making bread, and his recipe calls for 4/6 cups of flour. in any case, he has just a 1/3 cup estimating scoop.
Then the number of times that Gabriel needs to use his measuring scoop to make the bread will be given as,
⇒ (4/6) / (1/3)
⇒ (4/6) x (3/1)
⇒ 4 x 3 / 6
⇒ 12 / 6
⇒ 2 times

In rhombus ABCD, AB=12 and AC=22. Find the area of the rhombus to the nearest 10.
a) 195
b) 221.3
c) 105.5
d) 100.8
Answers
Answer:
c) 105.5 square units
Step-by-step explanation:
The area of a rhombus can be computed as half the product of the diagonal lengths.
__
Half the diagonal BD will be one leg of the right triangle formed by the diagonals and the sides of the rhombus. The length of that leg is found using the Pythagorean theorem:
a² +b² = c²
11² +b² = 12²
b² = 144 -121 = 23
b = √23 ≈ 4.796
This value is half the length of diagonal BD, so multiplying it by the length of diagonal AC will give the area of the rhombus.
Area = 1/2(AC)(BD) = (22)(4.796) ≈ 105.5 . . . . square units

Answer:
65.5584
Step-by-step explanation:
if you forget about the decimal place so you end up with
24 x 27316 you can complete that as long multiplication which youll end up with 655584.
then you count how many numbers you have after the decimal point in your equation and add them together so 2.4 has 1 (the 4) and 27.316 has 3 (the 3,1 and 6) which add 1 + 3 = 4
so you find the decimal place on your answer and you count back 4 places so
1 place ) 65558.4
2 place ) 6555.84
3 place ) 655.584
4 place ) 65.584
